There is a symbiotic relationship between payment methods and economic activity: the evolution of means of payment has historically favoured economic development, and similarly, the evolution of economic activity has led to the modernisation of means of payment.
Cash is the most popular means of payment worldwide, used in 85% of all transactions. However, despite the overwhelming prevalence of cash as a payment method, it is slowly declining. And that 15% of non-cash transactions (9.1% credit/debit cards and 4.6% direct debits/bank transfers) is where a disruption is now occurring which will affect the entire means of payment system.
